Transcript of The Nucleolus

photo (cc) Malte Sörensen @ flickr The Nucleolus and His Court. What is the Nucleolus???? The Nucleolus Control Center of the Cell Throughout the human body there are different “command centers,” for example, the brain. The brain sends and receives messages to tell the other parts of our bodies how to function and keep us alive. The same goes for cells, only this command center is called the nucleolus.
The nucleolus is a circular like organelle located in the nucleus part of the cell. It controls how the rest of the cell’s parts work to help keep the cell moving and alive. So I guess you could say that the nucleus is the “boss” of a cell. The History and Role of the Nucleolus Want a better idea of how the nucleolus works? Click below: The nucleolus is embedded in layers of different organelles. These consist of:
-Nuclear Envelope
-Nucleoplasm
-Chromatin
-Ribosomes
-Nuclear Pores  The Nucleolus was discovered by Antonie van Leeuwenhoek in 1719 and was later described by Franz Bauer in 1804, but was given the best description in 1831 by Scottish botanist Robert Brown in a talk during the Linnean Society of London. Mr. Brown was studying orchids under microscope when he saw an circular like section which he called the nucleus.
The nucleolus is made up of RNA. It’s function is to give permission and commands to the rest of the cell’s organelles.
